Abstract: 881,259. Automatic programme controls for newspaper stacking machines. BROOKHIRST IGRANIC Ltd. Dec. 8, 1959 [Dec. 29, 1958], No. 41674/59. Drawings to Specification Class 38 (6). [Also in Group XVI]  The control system for the newspaper stacking machine disclosed in Specification 781,652 is modified so that the number of newspapers per batch and the number of batches to a complete bundle can be varied either by a preset manual control or by a sequence of punched cards. A change-over switch is provided for the two modes of operation. Two electronic decade counters for units and tens respectively, are set either manually by wiper switches, or from a binary digital coded card to a number which when added to the number of newspapers per batch equals 100, e.g. it is set to 75 for 25 newspapers. As before, a photo-cell counts newspapers and at a predetermined count, an interceptor blade is advanced to collect the next batch and the first batch is dumped. Under programme control, a make-ready cycle precedes the first batch so that information for the size of the next batch has already been read from a second punched card and stored on relays, and the third card is now fed in, &c. The punched cards also control relays to determine whether a batch shall be added to a previous batch to form a bundle, or whether it should be removed on the conveyer. Under manual control the number of batches per bundle is determined by manual selection of a contact of a stepping switch which is energized each time a batch is dumped. On reaching the marked contact, the bundle is removed on the conveyer and the stepping switch is reset.

Abstract: 1344141 Passenger conveyers; endless conveyers R SALVADORINI 8 Sept 1971 [28 Dec 1970 25 Jan 1971 16 April 1971] 41907/71 Heading B8A A conveyer belt formed of a series of interlinked slats, has high speed sections 1a, 1b (Fig. 14), where the slats are in overlapped relation, and low speed sections where the slats are in lateral non-overlapping alignment, and where passengers may get on and off, at A and C. The return sections of the belt pass underground at A and C. In a modification (Fig. 1, not shown) the arrangement may consist of only half the system of Fig. 13. In another arrangement (Figs. 15 to 17, not shown) the whole conveyer may be disposed in a straight line. The slats may carry triangular extensions (Fig. 19, not shown) so that when the slats are overlapped the edges of the belt may present a continuous edge. The belt may be in the form of a number of parallel rods 3 (Figs. 3 and 4), each pivotally connected to one pivot of each of a series of parallel linkages 4. The latter are formed by pivotally connected members 5. The inclination between the members (5) (Figs. 5 to 8, not shown) of each linkage and hence the conveyer speed at that part of the belt is controlled by the relative positioning of rails (10), (10), on which the members (5) are supported by the action of pulley wheels (9), (11), carried by a fork (8) on which each member (5) is mounted. Further guidance is provided by a pair of pulleys (14) carried by each member (5) which engage a flange carried by the adjacent member(s). The conveyer may be driven by separate motors connected to driving wheels at positions along the conveyer. These motors may be connected in pairs in parallel, the pairs being connected to each other in series (Fig. 12, not shown). The conveyer of the invention may be used as a service conveyer to take passengers from a stationary position to a constant speed conveyer (Figs. 23, 24). The latter consists of an endless chain of load supporting plates 41. These are pivotally connected together and are supported on running wheels 42. Seats 48 are provided, and there is also room for standing passengers. A non-moving guard rail 52 carries a hand rail 53 which moves at the same speed as the conveyer. At the points where the conveyer comes adjacent to the service conveyer, the rail 52 ceases.

Filed: 1975-10-15
Abstract: 1517397 Memory addressing BENDIX CORP 15 Oct 1975 [15 Oct 1974] 42311/75 Heading G4A A memory system, e.g. a two dimensional matrix addressed by row and column indices, includes for each such index an integrator arranged to produce a sequence of addresses to access data items in a specified sequence which may be varied. The arrangement is used to cross-correlate corresponding points from two images stored in respective memories for sterophotogrammetry. Each of two memories 41, 43 has an associated addressing arrangement 40, 42 each of which comprises, for each address index (row and column), an integrator comprising three registers 45, 47, 49 coupled by adders 46, 48. In each of a series of cycles the contents of register 49 are added into register 47 and those of 47 into 45 whose output addresses the memory. Thus assuming that the whole contents of each register are added in each time, which need not be the case, the contents of the registers are: An=Ao+Bo n+Co n (n-1)/2 Bn=Bo+Co n Cn=Co where An, Bn, and Cn are the contents of registers 45, 47, 49 after n cycles and Ao, Bo, Co are the initial contents. By setting the initial contents appropriately a series of image points along a straight or curved line are accessed. The number of cycles is controlled by a sequence counter 71 decremented to zero or by a boundary address register which stops the operation when the output of the integrator reaches the boundary address. In a modification an incrementer is coupled to the output of each integrator so as to access a series of points surrounding each addressed point. Each of these points is multiplied by interpolation factors which are obtained from the less significant bits from the registers 45, 51, the more significant bits only providing the addresses. Corresponding image points from the two images are cross-correlated by multiplication 82 and addition 84 into a register 83. The arrangement shown is a special purpose device. The Specification also describes an interface including the addressing arrangement and cross-correlator which uses the memory of a separate data processor to store the image data, the interface being connected to input and output devices.
